Due to a boom in the dairy industry in Northeast China, the hay industry has been developing rapidly. Thus, it is very important to evaluate the hay quality with a rapid and accurate method. In this research, a novel technique that combines near infrared spectroscopy (NIRs) with three different statistical analyses (MLR, PCR and PLS) was used to predict the chemical quality of sheepgrass (Leymu...

Two experiments were conducted to evaluate the use of a closed system, fermentation apparatus (Daisy II incubator) and determine the effects of a yeast culture (YC) preparation (Saccharomyces cerevisiae) on in vitro microbial populations, diet digestion, and fermentation patterns in horses. In Exp. 1, 4 mature horses were fed a pelleted concentrate and alfalfa cubes in a 50:50 (%, as-fed) ratio...

The objective of this research was to compare values for digestible energy (DE) and metabolisable energy (ME) and apparent total tract digestibility (ATTD) of nutrients in 11 diets fed to both growing pigs and gestating sows. Three diets were based on corn, wheat or sorghum and eight diets were based on a combination of corn and soybean meal, canola meal, conventional distillers' dried grains w...

The near-infrared spectroscopy (NIRS) combined with modified partial least squares (modified PLS) regression was used for determining the neutral detergent fiber (NDF) and acid (ADF) fractions of chickpea (Cicer arietinum L.) seed. Fifty accessions (24 desi 26 kabuli types) fifty recombinant inbred lines F5:6 derived from a × cross were evaluated NDF ADF, scanned by NIRS. ADF values regressed a...

A nationally accepted standard hay test for alfalfa hay has included measurement of Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), Dry Matter (DM) and Crude Protein (CP). Total Digestible Nutrients (TDN) has typically been calculated directly from a fiber measurement, usually ADF. However, this is likely to change. While there are a range of points of view on forage testing, it is l...

In the present study we have developed the agar-fill method for the measurement of gastrointestinal-tract capacity (GTC) to replace the in vitro water-fill method. This would estimate GTC without using complex equipment and techniques, and can be applied to the measurement of GTC for small laboratory animals. We attempted to confirm the efficiency of the agar-fill method by investigating the re...

Objective. Improve the nutritional value of mechanized sugarcane residues inoculating the fungus Fomes sp. EUM1. Materials and methods. The fungus Fomes was inoculated according to a 0, 0.1, 0.2, and 0.3% (w/v) treatment and incubated at a temperature of 35°C for 7, 10 and 13 days. It was obtained DM, OM, CP, ash, NDF and ADF and the effective degradation of DM, NDF and ADF, with an experimenta...

Two experiments were performed to evaluate the effects of different levels of supplementation with a 50:50 (as-fed) mixture of molasses:crude glycerol on animal performance, total tract digestibility of nutrients, and ruminal in situ degradability of nutrients in beef heifers and steers consuming Tifton 85 Bermuda grass (Cynodon spp.) hay. For Exp. 1, 24 Angus crossbred heifers (380 ± 31 kg BW)...

this study was conducted to compare fungi and whole rumen microorganisms (wrm) digestibility of treated sugarcane pith by fungi and of buffalos and holstein cows. dry matter (dm), neutral and acid detergent fiber (ndf and adf) digestibilities of steam treated sugarcane pith (stp) by fungi and wrm were compared with a two-steps digestion technique, gas production (gp) and specific rumen fungi cu...
